Hi, my name is Jan Wilczek and I am an audio programmer and a researcher. Welcome to WolfSound!
WolfSound's mission is to provide high-quality, informative, and entertaining videos, articles, and courses on how to process sound by exploring mathematics, applying algorithms, and creating code in various programming languages. Topics include sound synthesis, digital signal processing, programming languages for audio (C, C++, Python, Rust), and audio effects. I am also sharing tips on how to learn fast and effectively. Make sure to visit https://www.thewolfsound.com/.
WolfSound enables everybody to learn about audio programming!
ABOUT THE VIDEO
In this video, I show you how to implement a plain (unoptimized) FIR filter in C++.
Learn how to
💡 Rewrite the FIR filter convolution formula,
💡 Pad the signals with zeros correctly, and
💡 Implement it in C++.
In case of any doubt in understanding, please, refer to the article above or ask a question in the comments 🙂
